The supporting member 80 is positioned upon the seat 65.

A rubber gasket is seated upon the supporting member 8U between the flanges 64 and 8|. 4,5 An' annular rubber plug 88 is seated in the tubular support 13 and hugs t-he nozzle 25.

An adjustable locking member for the cover 18 4is indicated in its entirety by the numeral 88, see Figs. 1, 3, 4 and 5. The member 98 comprises 60 the `hollow polygonal portion 9|, which has integral therewith the vertical cylindrical rotatable member 92. A. U shaped locking projection 93 is shown at the upper end of the member 92 and engages the locking groove 16. Adjacent to the 5I lower end of the member $2 are indicated the inclined locking cams 95.

A clamping band is indicated in its entirety by the numeral |00, see Figs. 1, 2, 5 and 8.

`The clamping band comprises the lower portion |03, which engages the fluted neck 63 of the receptacle 55. From the fluted portion |03 extends the vertical flange |04 and the latter joins with horizontal annular portion |05. The latter joins with the vertical member |06, having the top flange |01, forming the locking pocket |01a. From the member |06 extend the horizontal locking cams |00, which coact with' the in? clined locking cams 95. From the ends of the band extend the lugs ||5.

Upon the lugs ||5 is supported the handle bracket designated in its entirety by the numeral |20, see Figs. 1, 8 and 9.

The handle bracket comprises the triangular shaped side members |2|; which extend from the rear member |22, having the openings |23 for the lugs ||5. Cylindrical projections |26 extend from the sides of the'rear member |22 and a cylindrical projection |21 extends from the top of the member |22.

A handle is indicated at |30, the upper end of which is positioned between the lugs ||5. A male screw |3| coacts with the female screw |32. The said screws extend through the upper end of the handle to detachably clamp the same between the lugs ||5.

Referring to Fig. 10, a fragmentary portion of a modified inlet and outlet nozzle is indicated at The modified nozzle has integral therewith the disc member |40.having an axial threaded opening |4|. The cylindrical portion 46 of the stem 40 is again shown having the threaded end 41, which latter engages the threaded openi'ng |4|. The longitudinal conveying channels are again indicated at 40.

Referring -to Fig. 11 a fragmentary portion of Fig. 5 is shown with a modification. In this instance the detachable cover is of glass and is indicated in its entirety by the numeral 10a. 'Ihe top wall of the cover is indicated at which joins with the cylindrical wall |5|. At the upper end and outer surface of the latter is indicated the thread |52. A nut of metal is in threaded engagement with the thread |52. neck of the bulb shaped receptacle is again shown at 63. The clamping band is vagain shown at |00 with its appurtenances.

The adjustable member of the cover is indicated at 50 with its vertical cylindrical membe 62.

Referring to Fig. 12, the cover in this modification comprises the spherical shaped wall 10b,

which has the circular flange 10c'integral therewith.

The cylindrical wall of the cover 10b is indicated at with the foot |62 at its lower end. An adjustable locking member for the cover comprises the cylindrical wall with the polygonal head |66. Thewall |65 has again extending therefrom inclined locking cams 95, one of which is shown. The inner end of the top face of the head |66 extends below the circular flange 10c, and the said flange bears upon said head |66. The lower end of the Wall |65 is adapted to bear upon the foot |62.

To operate the percolator its members are assembled as indicated in Fig. 1, and the receptacle 2l with its nozzle 25 is removed from the bulb shaped receptacle 55. Water is poured into the ieceptacle 55 through the tubular support 13,

The uted and the receptacle 20 is again. placed in operative position. Next ground coffee is dropped into the receptacle 20 through the opening of its flange 22. The user then places the percolator upon a heated stove, by means of which the water in the receptacle 55 is heated. 'I'he vapor generated bears upon the water in the receptacle 55, and thereby it is forced up and through the nozzle 25,

Y the filtering material 38 and the perforatlons 34 of the hood 33, into the receptacle 20. The water then mixes with the ground coffee in said receptacle 20.

The receptacle 55 is now removed from the source of heat and a partial vacuum is formed in the said receptacle 55. The liquid coffee in the receptacle 20 is drawn into the receptacle 55, andv the coffee grounds, oils and other foreign matter, remain in the receptacle 20.

The receptacle 20 with its appurtenances is removed from the receptacle 55 and the liquid coffee in the latter is ready for use.

The fact that the hood 33 is madel of glass preserves the purity of the coffee and the tapered portion 45 of the stern 40 in contacting with the disc of filtering material 38 provides a tight connection, between the receptacles 20 and filtering material and prevents the coffee grounds entering the receptacle 55. The disc 38 of filtering material which is resilient provides a cushion between the cup shaped seat 24 and the flange 35 of the hood 33 to prevent the breakage of the receptacle 20 and injury to the connections between the stem 40 and the plug 50.

-The fact that the polygonal portion 9| is rotatable andthat its cylindrical member 92 bears upon the foot 15 instead of bearing on the rubber gasket 85, the cover 10 is easily removed, as there is no friction between the cover and gasket while the former is turned.

It will be noted that the coaction of the cams 95 and |06 forces the foot 15 of the cover 10 against the gasket 85, and provides a seal between the cover 10 and the receptacle 55 to enable a partial vacuum to be formed in said receptacle 55.

It is to be noted that the cover 10a may be made of glass in view of having connected thereto the polygonal nut |55 of. metal.

Various modifications mayl be made in the invention and the present exemplication is to be taken as illustrative and not limitative thereof.
